The invention provides a pharmaceutical composition for treating Alzheimer's
disease. The pharmaceutical composition is prepared from the following raw materials in parts by weight: 10-15 parts of
ginseng, 10-15 parts of rhizoma acori graminei, 10-15 parts of
polygala tenuifolia, 15-20 parts of rhizoma polygonati, 15-20 parts of
ginkgo leaves and 5-10 parts of
schisandra chinensis. Therefore, the
ginseng and the
ginkgo leaves jointly regulate a
cholinergic system and
cerebral blood flow, and the cognitive function is enhanced; the rhizoma acori graminei and the
ginkgo leaves cooperate to inhibit aggregation of beta-
amyloid protein, improve
cerebral circulation and relieve
neurotoxicity.
Polygonatum sibiricum and Chinese magnoliavine fruit protect
nerve cells through anti-oxidation and anti-inflammatory effects and reduce
nerve injury. Schizandrin further stabilizes a
neurotransmitter system and enhances the synergistic effect of other medicinal materials, a multi-layer treatment network of Abeta deposition inhibition,
cholinergic system regulation, anti-
inflammation and anti-oxidation and nerve protection is integrally formed, and the core
pathological link of the Alzheimer's
disease is comprehensively intervened, so that the cognitive function is improved, and the
disease progress is delayed.
